Classification is a process of particle sizing that depends on two physical parameters, particle sizes and particle specific gravity (SG). It is generally a wet process and involves a moving fluid that transports the material as the product is separated. Hydrocyclones and hydrosizers are the two main classifiers used in mineral processing.
